Administration of the MapR Database is done primarily via the command line (maprcli) or with the MapR Control System (MCS). Regardless of whether the MapR Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter
options. MapR Database administration is associated with tables, columns and column families, and table regions.

The MapR Data Access Gateway is a service that acts as a proxy and gateway for translating requests between lightweight
client applications and the MapR cluster. This section describes considerations when upgrading the service, how to modify
configuration settings, and how to administer and manage the service.

Wait for the running operations to complete before proceeding to the next
step.

Convert the volume from high_throughput replication type
to low_latency replication type using the maprcli command.

For example:

maprcli volume modify -name mvol1,mvol2 -replicationtype low_latency

Wait till replication type conversion is complete and all the containers of
the volume acquire a master. If necessary, run the following command to see if
replication type has been converted:

maprcli volume list -columns ReplTypeConversionInProgress,volumename

If
the conversion is complete, the ReplTypeConversionInProgress
flag will be set to false (0). For example, the
0 in the ReplTypeConversionInProgress
column in the following sample output indicates successful conversion of
corresponding volume in the volumename column:
